Answer:
carbon dioxide (CO2)
Explanation:
the burning or combustion of these fossil fuels creates gases that are released into the atmosphere. Of these gases, carbon dioxide (CO2) is the most common and is the gas most responsible for exacerbating the green- house effect that is changing global climate patterns.
When t=2, the ball has fallen d(2) = 16 (2²) = 64 feet .
When t=5, the ball has fallen d(5) = 16 (5²) = 400 feet .
Distance fallen from t=2 until t=5 is (400 - 64) = 336 feet.
Time period between t=2 until t=5 is (5 - 2) = 3 seconds.
Average speed of the ball from t=2 until t=5 is
(distance covered) / (time to cover the distance)
= 336 feet / 3 seconds = 112 feet per second.
That's what choice-C says.
In this item, we are asked to determine the speed of the bobsled given the distance traveled and the time it takes to cover the certain distance. This can mathematically be expressed as,
speed = distance / time
Substituting the given values in this item,
speed = (113 m) / (29 s)
speed = 3.90 m/s
<em>ANSWER: 3.90 m/s</em>
Beginning when the bottom of the object first touches the water,
and as it descends and more and more of it goes under, the
buoyant force on it increases during that time.
As soon as the object is completely underwater, it doesn't matter
how deep under it is, the buoyant force on it remains the same.
Answer:
Internal resistance = 0.545 ohm
Explanation:
As per ohm's law we know that
![V = iR](https://tex.z-dn.net/?f=V%20%3D%20iR)
here we know that
i = electric current = 2.75 A
V = potential difference = 1.50 Volts
now from above equation we have
![1.50 = 2.75 ( R)](https://tex.z-dn.net/?f=1.50%20%3D%202.75%20%28%20R%29)
now we have
![R = \frac{1.50}{2.75}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7B1.50%7D%7B2.75%7D)
![R = 0.545 ohm](https://tex.z-dn.net/?f=R%20%3D%200.545%20ohm)
